How long have you had this Psu?
You might want to have it checked out. If you happen to have or know someone who has a voltage meter, it should give you an indication to the health of your Psu. As good as it was in its day, it may or may not be giving out the wattage you may require. Better safe than sorry.
Just had a look on Extreme Power Supple Calculator. I factored in the following:
1x3750k Ocedx4.5Ghz.
2xSata hdd+1xdvd
4xfans
1x4670
Minimum Psu wattage required= 264w
Recommended Psu wattage required= 314w
So your Psu should be sufficient, but depending on its age, have it checked out.
